The pagination does not, liowever, always agree with that given by the same 

 author in his 'Lethsea Rossica,' p. 555, equalling p. 120, 



1856. In the ' Manual of the Mollusca,' S. P. Woodward assigns to each 

 family and genus of Carboniferous Lamellibranchs, published up to date, its 

 systematic position in the Mollusca, and where the genus is not known from other 

 formations gives a typical figure. In the appendix by Ralph Tate published 1880 

 various additions and alterations are made. 



1857. In the " Palseontological Report " in the ' Third Report of the Geological 

 Survey of Kentucky,' issued 1857, Cox describes and figures the following 

 Lamellibranchs from the Carboniferous beds of that State : 



JPecten Providencesis. 

 Area carhonaria. 

 Qervillia longispina. 

 Mi/alina pernaformis. 



Cardinia ? fracjilis. 

 Avicula rectalaterajna. 



— acosta. 

 Solemya soleniformis. 



In 1858 F. Shumard, in conjunction with G. C. Swallow, read a paper in 

 March, 1858, entitled " Descriptions of New Fossils from the Coal-measures of 

 Missouri and Kansas, which was published in the ' Transactions of the Academy 

 of Science of St. Louis,' vol. i, p. 159, 1856 — 1860.

In the same year R. P. Stevens' paper, " Description of New Carboniferous
